未找到列：1054未知列 - Laravel 5.1加入

I have three tables. work_orders, customers, and aircraft. In the work_orders table there are two fields customer_id and aircraft_id. I'm trying to retrieve the customers and aircraft data through the use of join. I am getting an array of errors, but they all seem to be pointed in the same direction and that is that the table cannot be found.

Here is my WorkOrderController index:

public function index(WorkOrder $workorder)
{
$workorder_array = $workorder
    ->join('work_orders as work', 'work.aircraft_id', '=', 'aircraft.id')
    ->join('work_orders as workorder', 'workorder.customer_id', '=', 'customers.id')
    ->select('work_orders.opened_date', 'customers.mobile', 'aircraft.year')
    ->get();

return view('work-orders.index', compact('workorder_array'));
}

And with this I get the following error:

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'aircraft.id' in 'on clause' (SQL: select work_orders.opened_date from work_orders inner join work_orders as work on aircraft.id = work.aircraft_id inner join work_orders as workorder on workorder.customer_id = customers.id)

I've tried switching work.aircraft_id with aircraft.id, because the Laravel Docs show it in that order, but that doesn't make any difference either. The only way I can get rid of this error is to remove my join statements.

I had the wrong table in the join statement. Here's what I should have had:

public function index(WorkOrder $workorder)
{
    $workorder_array = $workorder
        ->join('aircraft', 'work_orders.aircraft_id', '=', 'aircraft.id')
        ->join('customers', 'work_orders.customer_id', '=', 'customers.id')
        ->select('*')
        ->get();

    return view('work-orders.index', compact('workorder_array'));
}
